Mex007 - Tennantite on Quartz - Cobre Mine, Concepción del Oro, Zacatecas, Mexico

This superb classic specimen of tennantite has crystals measuring to 1 cm scattered on both sides of the quartz matrix. The tennantite crystals are some of the sharpest I've seen from this locality. There is minimal damage to this specimen - some natural contacting and one scuff of the quartz on the back side. 8.4 x 8.0 x 2.3 cm.
